MCQ
The correct statement regarding the basicity of arylamines is
  • A
    arylamines are generally more basic than alkylamines because of aryl group
  • B
    arylamines are generally more basic than alkylamines, because the nitrogen atom in arylamines is $sp-$hybridised
  • arylamines are generally less basic than alkylamines because the nitrogen lone-pair electrons are delocalised by interaction with the aromatic ring $\pi -$electron system
  • D
    arylamines are generally more basic than alkylamines because the nitrogen lone-pair electrons are not delocalised by interaction with the aromatic ring $\pi -$electron system.

Answer

Correct option: C.
arylamines are generally less basic than alkylamines because the nitrogen lone-pair electrons are delocalised by interaction with the aromatic ring $\pi -$electron system
c
Delocalized lone pair of nitrogen less basic
